To all whom t may concern.'

Be it known that I, WILHELM BI'r'rRoLr, a citizen ofthe German'Empire, anda res1- dent of Pforzheim, Germany, have invented new and useful Improvements in Soldering Machines, of which the following is a specilication. p

This invention relates to the soldering of chain mail or wire mesh by passing it continuously between two rows of flames with the least possible expenseof heat, without damaging the chain mail and soldering one piece ofchain mail 'by one procedure from endtoend. I

With this object in view the chain mail is mounted at its upper `edge hanging vertically from a vertically `moving carrier, so that it is adapted to traverse the llames in vertically hanging position.

The regular downward movement is preferably produced by suspending the upper edge of the chain mail on a horizontal carrier whichitself is suspended at its two .ends by twoy chains adapted to execute a feed motion in downward direction;

The chain mail is guided in proximity-of the'flames in order to smooththel small'folds `formed owing to the chain mail hanging down, as said folds wouldpreventthat all parts of the chain mail traverse exactly the right zone of highest temperature of the flame. For this purpose twofcylinders are providedl arranged at different heights above the flames and near'the same, said cylinders bearing from both sides against the chain mail with slight pressure but not pressing it between their surfaces, so that they can be made from metal resisting the heat near the flames without damaging the holders are preferably arranged for the chain mail so that, if the chain mail changes its direction of movement when getting upon the conveying .band one holder which has passed also through the flames and the guiding cylinders, drops automatically off the chains before they resume the movement in vertical direction, so vthat. uponv this holder can be rexed whilst the second holder withy the chain mail is passing with its chain malbetween the flames. In the drawing, Fig. l shows the machine in front elevation partly in sectionf Fig. 2 is a side elevation of the machinev partly in section, several parts being omitted.

-The uprights a, a fixed in a'base'plate a are connected at the top by a cross bar ce2. In the uprights a, a sprocket wheels b, b are arranged at the upper ends over which the chains c c are guided which `are further guided over the sprocket wheels'bl, b2 arranged 4upon the base plate. The sprocket wheels b2 are keyed upon a common shaft b3 which is revolved mechanically and may be revolved by hand.V On the kchains 0, c the holder bars d, d are fixed which have hooks d', d onrwhich the holders' f, fV for the chain mail vare suspended designed to carry by means of hooks or pins f the chain mail g.v The well -known burner` tubes m, m are'V fedy with combustible mixture through their hollowv axles. Each burner tube m `*is mounted upon rollers m4, m4A and a hori- Zontal reciprocating motion with regard to the chain mail (j is communicated to ksaid burner tubes from a cam cylinder m the curved groove of which acts upon the lower end of a stud ma fixed by a collar m3 upon the hollow axle of the corresponding burner.'

It andA h 'are the two upper f smoothing cylinders which are lmounted in the movable armsr 70,10 having counterweights Z, Z. The cylinders h., h are arranged the one above the. other at such a distance apart that they allow of the passage .of the. cary d and the holder f and do not clamp the wire chain between their` surfaces but press merely, without any counter pressure, against the hanging chain mail. Below the burner tubes the two guide cylinders q, Q are mounted in arms g2, g2 and g3, g3 so that they bring the chain mail somewhat out of its initial direction in order to assist in preventing the soldering together of several ad- 1,556,404v ,PAIEN-'r OFFICE.

jacent meshes. n is a conveyor band guided by cylindersA a', n and designed to deliver the cooled chain mail into the gutter p. A

The hand drive of the machine is used if llO small pieces of chain mail are to be soldered and if the holder has to be rapidly lowered from its highest position. The hooks or pins d are shaped to drop the holder f when assuming horizontal position on the conveyor band n. So each holder l.

might be agitated by a shaking motion.

Now what I claim and desire to secure by Letters Patent isl the following:

l. In a solde-ring machine of the described class the combination of a vertically guided chain mail carrier, adapted to carry chain mail to burners to solder' the same, means to suspend chain mail vertically hanging on said carrier, burners placed at both sides of the chain mail, means to move downward the said carrier and means to convey the mail sideward below the burners.

2. In a machine as described in claim l a smoothing cylinder above the burners touching with slight pressure the suspended chain mail.

3. In a soldering machine of the described Jclass, the combination of a vertically guided chain mail carrier adapted to carry chain mail to burners to solder the same, means to suspend chain mail vertically hanging on said carrier, burners placed at both sides ot the chain mail, smoothing cylinders arranged one above the other at opposite sides of the chain mail, means to move 'downward the said carrier and means to convey the mail sideward below the burners. y

4. In a machine as described in claim 1 a smoothing cylinder mounted below the burners.

5. In a machine as described in claim l two smoothing cylinders mounted below the burners at diierent heights one above the other.

6. In a machine of the described class an endless carrier to suspend chain mail vertically thereon and to convey said chain mail to burners to solder the same, two series ot burners, and means to move the mail and the carrier through the llames between the burners.

7. In a machine of the described class in claim 6, two carriers iXed at 4diiierent points to the moving elements.

S. In a machine as described in claim l a carrier consisting of an holder bar fixed to the moving means, a holder detachably fixed to the holder bar and provided with pins to insert into the upper edge of the chain mail.

9. In a soldering machine of the described class, the combination of a vertically guided chain mailA carrier adapted to carry chain mail to burners to solder the same, a holder bar fixed to the carrier, a holder detachably fixed to the holder bar, means to change the direction or the mail below the burners from the vertical direction and pins at the holder appropriately shaped to drop the holder at said change of direction.

l0. In a machine of the class described endless chains having a vertical downward motion, chain mail carriers iixed to said chains, rollers to direct the chains sideward at the lowerside of the machine, burners arranged above the plane of the said change or direction of the chains, a smoothing cylinder arranged above the burners, means to receive the chain mail below said plane and to direct it sideward from its vertical suspension plane.

11. In a machine for sol-dering. chain mail, an endless conveyor adapted to carry chain mail to heating means to sol/der the same, a heating means adapted to direct heat through a given path, means for feeding the conveying means through said heating path whereby the chain mail is heated to reduce the solder andy means for spacing the conveyer from the heating means.

In testimony that I claim the foregoing as my invention I have signed my name.
